MTB Derailleur Hangers FAQs

What makes BETD MTB derailleur hangers different?

Our MTB derailleur hangers are CNC-machined in the UK from aerospace-grade aluminium to ensure exceptional strength, precision, and reliability. Each hanger is built to exact tolerances for perfect alignment, delivering smoother and more accurate shifting. They’re stiffer and more durable than many OEM hangers, making them a trusted upgrade for riders who want dependable performance on technical trails.

How can I find the right MTB derailleur hanger for my bike?

Each frame and model has its own specific hanger design, so compatibility is crucial. The easiest way to identify the correct MTB derailleur hanger is to match your old one visually using the images on our website, or search by bike brand and model. With over 400 hanger options available, BETD covers a wide range of mountain bike manufacturers. If you’re uncertain, our expert team can confirm the exact fit for your frame.

Should I replace or realign a bent MTB derailleur hanger?

If your hanger has been knocked or slightly misaligned, it can sometimes be straightened with a derailleur alignment tool. However, once aluminium has been bent, its strength is compromised. For consistent shifting and long-term reliability, replacing a bent hanger with a new BETD MTB derailleur hanger is the better option.

When should I replace my MTB derailleur hanger?

If you notice poor shifting, chain skipping, or misalignment after a crash or impact, it’s likely time to replace your hanger. Even a minor bend can cause issues across the drivetrain. Regular checks after rough rides or transport can help prevent damage to your derailleur and frame. Keeping a spare MTB derailleur hanger on hand is always recommended, especially for riders tackling remote or technical trails.

Do you stock MTB derailleur hangers for older or discontinued bikes?

Yes. BETD produces replacement MTB derailleur hangers for a wide range of frame models, including older and discontinued bikes no longer supported by the original manufacturers. Our extensive collection ensures riders can maintain and restore their existing mountain bikes without compromise on quality or fit.

Why choose BETD for MTB derailleur hangers?

Every hanger is CNC-machined in the UK, anodised for corrosion resistance, and built to maintain perfect alignment under the stresses of mountain biking.
